David suggests it's more intuitive to return non-zero on
failures, and zero on success.
No need to introduce tail 'return 0' in functions, they will
return the exit code of the last command anyway.

iproute2 print_skbmod() prints the configured ethertype using format 0x%X:
therefore, test 9aa8 systematically fails, because it configures action #4
using ethertype 0x0031, and expects 0x0031 when it reads it back. Changing
the expected value to 0x31 lets the test result 'not ok' become 'ok'.

====================
pull-request: bpf-next 2018-03-03
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Extend bpftool to build up CFG information of eBPF programs and add an
option to dump this in DOT format such that this can later be used with
DOT graphic tools (xdot, graphviz, etc) to visualize it. Part of the
analysis performed is sub-program detection and basic-block partitioning,
from Jiong.
2) Multiple enhancements for bpftool's batch mode, more specifically the
parser now understands comments (#), continuation lines (\), and arguments
enclosed between quotes. Also, allow to read from stdin via '-' as input
file, all from Quentin.
3) Improve BPF kselftests by i) unifying the rlimit handling into a helper
that is then used by all tests, and ii) add support for testing tail calls
to test_verifier plus add tests covering all corner cases. The latter is
especially useful for testing JITs, from Daniel.
4) Remove x64 JIT's bpf_flush_icache() since flush_icache_range() is a noop
on x64, from Daniel.
5) Fix one more occasion in BPF samples where we do not detach the BPF program
from the cgroup after completion, from Prashant.
